Mistress Anni did not want this guy to think that eavesdropping was right. She warned him first but he did not heed her warning. She was pissed at him and she used her female domination fetish to deal with him. The guy was humiliated and he was degraded the way she wanted and by the end of the day, he had to agree with her and stop being an eavesdropper.
Mistress Anni had an issue with her man as he had not fulfilled his promise to her. She was pissed and she had to express her displeasure at the turn of events. The mistress made sure that she teased him and since she knew him well, it was easy for her. The mistress loved how she was able to turn him on but leave him hanging. She left him high and dry as punishment.
